The fitting 7 is provided with one or morekpassages y9; l'eading'fromits eX- terior and .discharging into the upper end of s the harr'el'l.' The'fftting? is'pro'vided'with I, aeentral' longitudinal opening or hole extendingth'erethrou h,n whiehis longitudinally slidable a tubu. ar Valve 10. The tting 7 is f eading from the eentralhole and discharging into; the eonduetingpipe '8. vTheyalye 1 is provided with a Ihorizontal peripheral ange vv12, l'disposed above and adapted whenk the vvValve is properlylpositione'dtoelose.the pasl sages`l or ports- 1 'The lower end of the valve .101be`l0w the' passages 9 is'externally screwthreaded andhastt'ed toit arin'g 13, 'forming part of .the valve 'andwhen the Valve is inl the upper yposition ada ted Ato close the passages v9.' Whenfthe' ya Ve 1(7)V is reciprolfdue'tin'gLpipel8'." When the Valve 1() is in the "lower position', the flange '12 covers the ports '11 an vprevents baolowirom the conducting-'pi e 8 through saidp'orts.- The ring 13 is consi erably smaller in diameter than the in- -t'eriorvof the barrel 1,1 thus permitting the liq-4 uid to enterthe barrel Jr'romthepassages 9 around the periphery of said ring. AWhen the Valve 10 -is in the lower 'position,' the'y liquid may also pass'from vthe passages`9, through royidfed' also with one or more passages 11,

catedyertioallygthe'passages 9 and 11 are.

thefa'nnular passagefl', into'the! harrel 1.' rWh'en'the piston 15 is rmoved downwardly,

upwardly rorn`-the"bar1"el"1 through the annular'spaeey 16",I-p'orts 11,`and intolthe con- IOO the valve 10 will be moved by gravity or by the weight of water resting upon it to the downward position, thus closing the ports 11 and opening the passages 9, permitting the barrel to fill from its up er end. When the piston is moved upward y, the check-valve will be raised, permitting the water to fill the barrel from the lower end through the fitting 2, and the ressure of the water above the piston will orce the valve 1() to the position shown in solid lines in Fig. 1, closing the passages 9 and permitting the water above the piston to pass through the space 16 and ports 11 through the conducting-pipe 8.

In order that the valve may more certainly move with the piston-rod 14, the uph perend of the vlave 10 has secured to it a stuffing-box 17, whichl encircles the pistonrod 14 and compresses packing material 18 against the upper end of the valve 10 and around the periphery of the piston-rod, the

friction of the packing 18 serving to move the valve with the rod, but permitting slidinO' of the rod through the valve after the valve as become seated.

The upper end of the piston-rod 14 has secured to it, preferably by a screw-thread connection, the lower end of a tubular fitting 19, to the upper end of which is secured in any desirable manner the lower'end of the connecting-rod 20 of the pump.` The fitting 19 is provided with one or more-lateral discharge-openings 21, through which the water discharged from the piston-rod escapes into the'conducting-pipe 8. In the fitting 19 is `mounted a vertically-movable check-valve 22, provided with a central vertical stem 23, vertically movable in a central hole rovided in a horizontal disk 24, secured in t e fitting 19 below the connecting-rod 2O and above the o enings 21.

` en the piston 15 is moveddownwardly,

the water in the barrel below the piston forces the check-valve 5 to its seat and prevents downflow of the'water from the barrel. rlhe `water, therefore, which is below the piston the ground by'thejgsucceedin instalments of water taken into ,the said, lcon noting-pipe. It lwill thus be seen that when the piston is re- "ciprocated the valve 10 will be reciprocated,

S5;and .water taken in through the passages 9 upon the downward movement of the piston 'will upon theupward movement thereof be forced through vthe channels described into the conducting-pipe 8. The water drawn into the barrel past the val-ve 5 during the upwardrnovr'nent of the/piston will upon the downward movement thereof be forced through the piston and piston-rod, past the water, therefore, is pumped upwardly in a substantially continuous stream.

Any suitable mechanism may be employed for reciprocating the connecting-rod 20, and the conducting-pipe 8, which may be of any desired length, may be supported in any convenient manner. The lower end of the fitting 2 is preferably externally screw-threaded for the afiixing thereto of a strainer (not shown, but which may be of any ordinary pattern.)

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
